Oddness with 16295

["Lay, James" <james.lay () wincofoods com>]

So this is weird....looking at this hit:

 

11/10-10:38:18.976338  [**] [1:16295:2] WEB-CLIENT Kaspersky antivirus
library heap buffer overflow - without optional fields [**]
[Classification: Attempted User Privilege Gain] [Priority: 1] {TCP}
204.11.109.23:80 -> 10.21.0.16:64385

 

Fairly certain it's an fp, but...when I hit the pcap dump file, it
doesn't show....here's consecutive hits in the alert file:

 

11/10-10:37:25.096951  [**] [1:12280:2] WEB-CLIENT VML source file
memory corruption [**] [Classification: Attempted User Privilege Gain]
[Priority: 1] {TCP} 67.23.129.249:80 -> 10.21.0.16:64185

11/10-10:37:25.131950  [**] [1:12280:2] WEB-CLIENT VML source file
memory corruption [**] [Classification: Attempted User Privilege Gain]
[Priority: 1] {TCP} 67.23.129.249:80 -> 10.21.0.16:64185

11/10-10:38:18.976338  [**] [1:16295:2] WEB-CLIENT Kaspersky antivirus
library heap buffer overflow - without optional fields [**]
[Classification: Attempted User Privilege Gain] [Priority: 1] {TCP}
204.11.109.23:80 -> 10.21.0.16:64385

11/10-10:39:35.643464  [**] [119:14:1] (http_inspect) NON-RFC DEFINED
CHAR [**] [Priority: 3] {TCP} 10.21.0.16:64686 -> 66.211.180.40:80

 

And from the pcapfile:

sudo tcpdump -n -s 1524 -r internettcpdump.pcap.1289401395

10:37:25.096951 IP 67.23.129.249.80 > 10.21.0.16.64185: Flags [.], ack
1081895485, win 4789, length 1400

10:37:25.131950 IP 67.23.129.249.80 > 10.21.0.16.64185: Flags [.], ack
1, win 4789, length 1400

10:39:35.643464 IP 10.21.0.16.64686 > 66.211.180.40.80: Flags [.], ack
2261207081, win 65535, length 536

 

So where did 16295 go?  A quick check for that IP gives nothing:

[10:48:24 jlay@goids:~/log$] sudo tcpdump -n -s 1524 -r
internettcpdump.pcap.1289401395 ip and host 204.11.109.23

reading from file internettcpdump.pcap.1289401395, link-type EN10MB
(Ethernet)

[10:50:21 jlay@goids:~/log$]
